The Colts recorded their first shutout of a team since the 2008 season, and Pagano feels that his defense is starting to show progress that could make them contenders in the AFC.
"We're just starting to get a glimpse of what we envisioned when we got together a couple years ago," Pagano told reporters.
"Looks like that monster is starting to rear its head a little bit. We just have to stay humble, keep working and get better."
Pagano's side are 5-2 in their season after their win over the Bengals.
